[0014] A method for using a hydrogenated styrene-butadiene block copolymer impurity removal device comprises the following steps: Step 1: Inject the raw material into the filter frame through the feed pipe, and filter the impurities in the raw material through the filter plate. At the same time, the motor rotates to drive the rotating rod to rotate, and the rotating rod rotates to drive the filter frame to rotate. The centrifugal force generated by the rotation of the filter frame is used to perform secondary separation on the impurities in the raw material, thereby improving the impurity removal effect; Step 2: The rotating rod rotates to rotate the reciprocating thread groove, which drives the thread plate to reciprocate up and down, and the up and down reciprocating movement of the thread plate drives the filter plate to reciprocate up and down. The up and down reciprocating movement of the filter plate scrapes off the impurities attached to the inner wall of the filter frame to prevent the impurities from clogging the inner wall of the filter frame and affecting the impurity removal effect of the filter frame; Step 3: The filter plate moves upward, driving the elastic expansion block to move upward. The elastic expansion block moves upward and contacts the top of the inner wall of the reactor. The free end of the elastic expansion block is pushed to contract by the reverse force. The free end of the elastic expansion block moves downward, driving the rotating plate to rotate downward. The rotating plate rotates downward, driving the fixed frame to move away from the rotating rod. Step 4: The fixed frame moves away from the rotating rod, driving the annular plate to move away from the rotating rod. The two annular plates move away from the rotating rod to push away the impurities scraped off the filter plate, preventing the impurities from being in the filter frame all the time, resulting in reduced filtering effect of the filter frame and affecting the impurity removal efficiency.

[0015] The present invention provides a device and method for removing impurities from hydrogenated styrene-butadiene block copolymers. The device and method have the following beneficial effects: (1) This invention uses the centrifugal force generated by the rotation of the filter frame to perform secondary separation on the impurities in the raw material, thereby improving the impurity removal effect. At the same time, the reciprocating rotation of the threaded groove will drive the threaded plate to move up and down, and the up and down reciprocating movement of the threaded plate will drive the filter plate to move up and down. The up and down reciprocating movement of the filter plate will scrape off the impurities attached to the inner wall of the filter frame to prevent the impurities from clogging the inner wall of the filter frame and affecting the impurity removal effect of the filter frame. The impurities scraped off the filter plate are pushed away by moving the two circular plates away from the rotating rod to prevent the impurities from being in the filter frame all the time, resulting in a decrease in the filtering effect of the filter frame and affecting the impurity removal efficiency.

[0016] (2) In the present invention, the rotation of the filter frame will drive the rotation of the elastic telescopic rod, and the rotation of the elastic telescopic rod will drive the rotation of the elastic telescopic scraper. The rotation of the elastic telescopic scraper will drive the scraping of the raw materials adhering to the inner wall of the reactor to prevent the raw materials from adhering to the inner wall of the reactor. The formation of the adhesion layer will affect the heat conduction of the inner wall of the reactor, resulting in uneven temperature distribution, which will affect the reaction rate and may cause instability in the reaction process. At the same time, the contraction of the free end of the elastic telescopic scraper will push away the raw materials adhering to the elastic telescopic scraper to prevent the raw materials from adhering to the free end of the elastic telescopic scraper, resulting in poor subsequent scraping effect and affecting the impurity removal effect.

[0017] (3) This invention increases the contact area between the adsorbent and the fluid by moving the adsorption plate up and down. The up and down movement of the adsorption plate helps solve the problem of local saturation of the adsorbent, making the adsorption process more uniform and avoiding the adsorbent from losing its activity after being saturated in a local area. In this way, more efficient impurity removal can be achieved in a shorter time. At the same time, vibration is generated by the contact between the convex block and the sliding convex plate. The vibration can improve the contact time and contact area between the adsorption plate and the impurities, thereby improving the adsorption efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] A sliding block 164 is slidably installed on the inner wall of the top of the circular concave plate 163, a sliding rod 165 slides through the surface of the circular concave plate 163, a pulley 166 is rotatably installed on the inner wall of the sliding rod 165, and a circular push plate 167 is fixedly installed on the bottom of the sliding rod 165. The free end of the elastic telescopic scraper 162 will contract to push away the raw materials attached to the elastic telescopic scraper 162, preventing the raw materials from adhering to the free end of the elastic telescopic scraper 162, resulting in poor subsequent scraping effect and affecting the impurity removal effect.

When the adsorbent in a certain area adsorbs too much material and reaches the upper limit of its adsorption capacity, this area enters an "oversaturated" state. At this time, the adsorbent in this area has no more The method cannot effectively adsorb more substances, resulting in reduced adsorption efficiency, and some impurities may even fail to be effectively removed.

[0030] A method for using a hydrogenated styrene-butadiene block copolymer impurity removal device comprises the following steps: Step 1: The raw material is injected into the filter frame 7 through the feed pipe 3, and the impurities in the raw material are preliminarily filtered through the filter plate 11. At the same time, the motor 5 rotates to drive the rotating rod 6 to rotate, and the rotating rod 6 rotates to drive the filter frame 7 to rotate. The centrifugal force generated by the rotation of the filter frame 7 is used to perform secondary separation on the impurities in the raw material, thereby improving the impurity removal effect; Step 2: The rotating rod 6 rotates the reciprocating thread groove 9, and the reciprocating thread groove 9 rotates, which drives the thread plate 8 to reciprocate up and down, and the up and down reciprocating movement of the thread plate 8 drives the filter plate 11 to reciprocate up and down, and the up and down reciprocating movement of the filter plate 11 scrapes off the impurities attached to the inner wall of the filter frame 7 to prevent the impurities from clogging the inner wall of the filter frame 7 and affecting the impurity removal effect of the filter frame 7; Step 3: The filter plate 11 moves upward, driving the elastic expansion block 13 to move upward. The elastic expansion block 13 moves upward and contacts the top of the inner wall of the reactor 1. The free end of the elastic expansion block 13 is pushed to contract by the reverse force. The free end of the elastic expansion block 13 moves downward, driving the rotating plate 15 to rotate downward. The rotating plate 15 rotates downward, driving the fixing frame 14 to move away from the rotating rod 6. Step 4: The fixing frame 14 moves in the direction away from the rotating rod 6, driving the annular plate 12 to move in the direction away from the rotating rod 6. The two annular plates 12 move in the direction away from the rotating rod 6 to push away the impurities scraped off the filter plate 11, preventing the impurities from being in the filter frame 7 all the time, resulting in reduced filtering effect of the filter frame 7 and affecting the impurity removal efficiency.

[0031] When the present embodiment is working, the rotation of the filter frame 7 drives the elastic telescopic rod 161 to rotate, the rotation of the elastic telescopic rod 161 drives the elastic telescopic scraper 162 to rotate, the rotation of the elastic telescopic scraper 162 drives the raw materials adhering to the inner wall of the reactor 1 to be scraped off, and prevents the raw materials from adhering to the inner wall of the reactor 1. The formation of the adhesion layer will affect the heat conduction of the inner wall of the reactor 1, resulting in uneven temperature distribution, which will affect the reaction rate and may cause instability in the reaction process, thereby affecting the impurity removal and the quality of the final product. At the same time, when the annular plate 12 moves away from the rotating rod 6, it will push the sliding block 164 to move away from the rotating rod 6. The movement of the movable block 164 in the direction away from the rotating rod 6 will push the pulley 166 and the sliding rod 165 to move downward, and the downward movement of the sliding rod 165 will drive the annular push plate 167 to move downward, and the downward movement of the annular push plate 167 will push the elastic telescopic scraper 162 to move toward the inner wall of the reactor 1. The movement of the elastic telescopic scraper 162 toward the inner wall of the reactor 1 will cause the free end of the elastic telescopic scraper 162 to shrink, and the shrinkage of the free end of the elastic telescopic scraper 162 will push away the raw materials attached to the elastic telescopic scraper 162, preventing the raw materials from adhering to the free end of the elastic telescopic scraper 162, resulting in poor subsequent scraping effect and affecting the impurity removal effect.

[0032] The elastic retractable scraper 162 moves toward the inner wall of the reactor 1, driving the push plate 175 to move toward the inner wall of the reactor 1. The push plate 175 moves toward the inner wall of the reactor 1, which pushes the triangular block 174 to move downward. The downward movement of the triangular block 174 drives the adsorption plate 173 to move downward. When the push plate 175 is separated from the triangular block 174, the elastic force of the elastic retractable connecting rod 171 drives the fixed plate 172 and the adsorption plate 173 to reset. The contact area between the adsorbent and the fluid is increased by the up and down movement of the adsorption plate 173. The up and down movement of the adsorption plate 173 helps solve the problem of local saturation of the adsorbent. The problem is that the adsorption process is made more uniform, and the adsorbent is prevented from losing its activity after being saturated in a local area. In this way, more efficient impurity removal can be completed in a shorter time. At the same time, the rotation of the filter frame 7 will drive the elastic telescopic connecting rod 171, the fixed plate 172 and the adsorption plate 173 to rotate. The adsorption plate 173 moves downward and rotates, which will drive the protrusion 176 to move downward and rotate. The protrusion 176 moves downward and rotates to contact the sliding protrusion 178. Vibration is generated by the contact between the protrusion 176 and the sliding protrusion 178. The vibration can improve the contact time and contact area between the adsorption plate 173 and the impurities, thereby improving the adsorption efficiency.

9. A method for using a hydrogenated styrene-butadiene block copolymer impurity removal device, using the hydrogenated styrene-butadiene block copolymer impurity removal device according to claim 8, characterized in that: The following steps are involved: Step 1: injecting the raw material into the filter frame (7) through the feed pipe (3), and preliminarily filtering the impurities in the raw material through the filter plate (11). At the same time, the motor (5) rotates to drive the rotating rod (6), and the rotating rod (6) rotates to drive the filter frame (7). The centrifugal force generated by the rotation of the filter frame (7) is used to perform secondary separation on the impurities in the raw material, thereby improving the impurity removal effect. Step 2: The rotating rod (6) rotates the reciprocating thread groove (9), and the reciprocating thread groove (9) rotates, which drives the thread plate (8) to move up and down, and the up and down reciprocating movement of the thread plate (8) drives the filter plate (11) to move up and down, and the up and down reciprocating movement of the filter plate (11) scrapes off impurities attached to the inner wall of the filter frame (7), thereby preventing the impurities from clogging the inner wall of the filter frame (7) and affecting the impurity removal effect of the filter frame (7); Step 3: The filter plate (11) moves upward, driving the elastic expansion block (13) to move upward. The elastic expansion block (13) moves upward and contacts the top of the inner wall of the reactor (1). The free end of the elastic expansion block (13) is pushed to contract by the reverse force. The free end of the elastic expansion block (13) moves downward, driving the rotating plate (15) to rotate downward. The rotating plate (15) rotates downward, driving the fixed frame (14) to move in a direction away from the rotating rod (6). Step 4: The fixing frame (14) moves in a direction away from the rotating rod (6) to drive the annular plate (12) to move in a direction away from the rotating rod (6). The two annular plates (12) move in a direction away from the rotating rod (6) to push away the impurities scraped off the filter plate (11), thereby preventing the impurities from being retained in the filter frame (7) and causing the filtering effect of the filter frame (7) to be reduced, thereby affecting the impurity removal efficiency.
